I am by no means a power twitter user, but this is hands-down, THE best application for twitter out there, and I can see how useful it would be for a power user. The widget is far more versatile, allowing you to choose where you want to go, rather than showing a few recent tweets. The UI is just plain intuitive, the icons given to buttons by the developer need no caption to be understood, and without captions it looks very clean. And then there's plugins for flickr, buzz, twitpic, etc. The developer is definitely dedicated and the app is updated constantly. If you're looking for a twitter app, look no further, you've found it!
